DETAILED DESCRIPTION

FIG. 1 depicts a vehicle 100. While the vehicle 100 is depicted as a truck, it is envisioned the vehicle 100 may be any vehicle. The vehicle 100 may include a tractor unit or a cab 102 and a trailer 104. The cab 102 may be connected to the trailer 104 to provide a pulling force for moving the vehicle 100.

The cab 102 includes one or more pairs of wheel assemblies 106 and a power source 108. The one or more wheel assemblies 106 may be adapted to support the cab 102 and the trailer 104. The power source 108 may be carried by the trailer 104.

The trailer 104 includes a generally cylindrical tank 110, one or more pairs of wheel assemblies 112, a landing gear 114, and a nozzle assembly 116. The one or more wheel assemblies 112 may be adapted to support the tank 110. Furthermore, when the vehicle 100 is stationary, the landing gear 114 may be adapted to provide further support to the tank 110. The tank 110 includes a hollow interior for transporting material. The shape and size of the tank 110 will be dependent upon the material being transported. The nozzle assembly 116 may be on a side of the tank 110 and may be in open communication with the hollow interior of the tank 110. Hoses may be selectively engaged with the nozzle assembly 116 to transfer the material (i.e., fuel, liquid, grain, etc.) from the hollow interior of the tank 110 to a storage container. Although the trailer 104 is referred to herein as including a cylindrical tank 110, it is envisioned that the trailer 104 may include non-cylindrical trailers (i.e., rectangular cargo trailers). The trailer 104 further includes a first hose holder 118 connected to the tank 110. As shown in FIG. 2 , the first hose holder 118 is adapted to hold one or more hoses 202. As further shown in FIG. 2 , the trailer 104 includes a second hose holder 204 connected to the tank 110 and adapted to hold one or more hoses 202.

Returning to FIG. 1 , the trailer 104 further includes and carries a safety arm holder 120 and one or more safety arm receivers. As will be discussed in further detail below, in one embodiment, the safety arm holder 120 is connected to the first hose holder 118 and the second hose holder 204. In another embodiment, the safety arm holder 120 may be mounted anywhere on any outer surface of the vehicle 100 (i.e., adjacent to the nozzle assembly 116). The safety arm holder 120 may be adapted to retain one or more safety arms 124 outside of the vehicle 100 while the vehicle 100 is stationary or moving. While the safety arm holder 120 is shown holding four safety arms 124, it is envisioned that the safety arm holder 120 may hold any number of safety arms 124 (i.e., 1, 3, 6, 9, 10, etc.). In one embodiment (FIG. 1 ), the safety arm holder 120 may be in electrical communication with the power source 108. Although the power source 108 is shown within cab 102, it is envisioned that the power source 108 may be located elsewhere on the vehicle 100. It is further envisioned that the power source 108 may be external from the vehicle 100.

As will be discussed in further detail below, the safety arm receivers are adapted to couple to a safety arm 124 such that, when coupled, a safety arm receiver provides vertical and horizontal support for a safety arm 124 so that a safety arm 124 may extend from the vehicle 100 without any support structure depending from the safety arm 124.

The trailer 104 further includes a bracket holder 126. Although the bracket holder 126 is shown connected to the first hose holder 118, it is envisioned that the bracket holder 126 may be connected to the second hose holder 204 or the tank 110. Furthermore, the bracket holder 126 may be adapted to contain a bracket 128 and a bracket support 130. As will be discussed in further detail below, the bracket 128 may be adapted to receive one or more safety arms 124 and the bracket support 130. The bracket support 130 may be adapted to support the bracket 128.

FIG. 2 depicts the tank 110. The tank 110 includes a first end 206, a second end 208, a first side 210, a second side 212, a top side 214, and a bottom side 216. The first end 206 faces the cab 102 and the second end 208 is opposite the first end 206. A central longitudinal axis 218 extends between and through the first end 206 and the second end 208 thereby defining a longitudinal direction between the first end 206 and the second end 208. The first side 210 is opposite the second side 212 and a central transverse axis 220 extends between and through the first side 210 and the second side 212 thereby defining a transverse direction between the first side 210 and the second side 212. The top side 214 is opposite the bottom side 216 and a central vertical axis 222 extends between and through the top side 214 and the bottom side 216 thereby defining a vertical direction between the top side 214 and the bottom side 216. The central longitudinal axis 218, the central transverse axis 220, and the central vertical axis 222 are oriented at right angles relative to one another.

FIG. 3 depicts safety arms 124 in a stored position. The safety arm holder 120 slidably receives and supports the safety arms 124 and the safety arms 124 extend parallel to the central transverse axis 220 and perpendicular to the central longitudinal axis 218

The safety arm holder 120 includes a first holder 302 a distance away from a second holder 304. The distance between the first holder 302 and the second holder 304 is less than a length of a safety arm 124. As such, a safety arm 124 may be carried and retained by the first holder 302 and the second holder 304 when the vehicle 100 is stationary or moving.

In one embodiment, the first holder 302 may be connected to the first side 210 of the tank 110 and the second holder 304 may be connected to the second side 212 of the tank 110. In this embodiment, the first holder 302 may be connected to a bottom surface 306 of the first hose holder 118 and the second holder 304 may be connected to a bottom surface 308 of the second hose holder 204. The first holder 302 and the second holder 304 are further connected to a mounting member 310 and 312 respectively. The mounting members 310 and 312 are connected to the tank 110. In another embodiment, the first holder 302 and the second holder 304 may be anywhere on the vehicle 100 (i.e., on the first side 210 of the tank 110, on the second side 212 of the tank 110, etc.).

The first holder 302 includes a first end 314, a second end 316 opposite the first end 314, a top end 318, and a bottom end 320 opposite the top end 318. The first end 314 extends longitudinally relative to the central vertical axis 222 from the bottom surface 306 to the bottom end 320 and the second end 316 extends longitudinally relative to the central vertical axis 222 from the mounting member 310 to the bottom end 320. Opposing inner surfaces 322 extend longitudinally relative to the central vertical axis 222 from the top end 318 to the bottom end 320 and longitudinally relative to the central longitudinal axis 218 from the first end 314 to the second end 316. The first end 314 and the second end 316 are open ended such that when a safety arm 124 is moved in either direction of arrow A, a safety arm 124 may pass through the first holder 302.

The first holder 302 further includes a first rack 324 and a second rack 326. The first rack 324 is vertically above second rack 326. Stated another way, the second rack 326 is vertically below the first rack 324. The first rack 324 and the second rack 326 extend between the first end 314 and the second end 316 of the first holder 302. Furthermore, the first rack 324 and the second rack 326 are adapted to slidably receive and support one or more safety arms 124.

The second holder 304 includes a first end 328, a second end 330 opposite the first end 328, a top end 332, and a bottom end 334 opposite the top end 332. The first end 328 extends longitudinally relative to the central vertical axis 222 from the bottom surface 308 to the bottom end 334 and the second end 330 extends longitudinally relative to the central vertical axis 222 from the mounting member 312 to the bottom end 334. Opposing inner surfaces 336 extend longitudinally relative to the central vertical axis 222 from the top end 332 to the bottom end 334 and longitudinally relative to the central vertical axis 222 from the first end 328 to the second end 330.

The second holder 304 further includes a first rack 338 and a second rack 340. The first rack 338 is vertically above second rack 340. Stated another way, the second rack 340 is vertically below the first rack 338. The first rack 338 and the second rack 340 extend between the first end 328 and the second end 330 of the second holder 304. The first rack 338 and the second rack 340 are adapted to slidably receive and support one or more safety arms 124.

In one embodiment only the second end 330 of the second holder 304 is open ended. In this embodiment, when placing a safety arm 124 into the stored position, a safety arm 124 enters the safety arm holder 120 from the first side 210 of the tank 110, passes through the first end 314 of the first holder 302 and through the second end 330 of the second holder 304. Stated another way, a safety arm 124 first enters the first holder 302 then enters the second holder 304.

In another embodiment, the first end 328 and the second end 330 of the second holder 304 are open ended. In this embodiment, when placing a safety arm 124 in a stored positon, a safety arm 124 may enter the safety arm holder 120 from the first side 210 or the second side 212 of the tank 110. Stated another way, a safety arm 124 may first pass through the first holder 302 and then into the second holder 304 or may first pass through the second holder 304 and then into the first holder 302.

In one embodiment (FIG. 3 ), the second holder 304 may be in electrical communication with the power source 108. In this embodiment, the second holder 304 includes a charging dock 342 and a safety arm 124 includes and carries a battery 344. The charging dock 342 is carried by the trailer 104 and is in electrical communication with the power source 108 and is adapted to charge the battery 344 of a safety arm 124 when a safety arm 124 is connected to the charging dock 342. In this embodiment, the battery 344 is in electrical communication and supplies power to a light source 345 of a safety arm 124.

The charging dock 342 includes a number of receptacles or channels 346. The number of channels 346 may depend upon the number of safety arms 124 that the safety arm holder 120 is adapted to retain. For example, in the embodiment shown in FIG. 2 , the safety arm holder 120 is adapted to retain four safety arms 124. Hence, the charging dock 342 may contain four channels 346. It is envisioned that the charging dock 342 may contain any number of channels 346 (i.e., 1, 3, 6, 9, 10, etc.). The channels 346 are defined by a surface 348. The surface 348 extends from a side surface 352 to an opening 354. The surface 348 defines a shape of a channel 346. The shape of a channel 346 may correspond to a shape and a dimension of a safety arm 124. For example, in the embodiment shown in FIG. 4 , a safety arm 124 has a circular shape. As such, a channel 346 may be circular with a diameter that corresponds to a diameter of a safety arm 124. Due to the corresponding shape and dimension, when a safety arm 124 is in the stored position, a portion of the safety arm 124 nests within the channel 346.

In the embodiment shown in FIG. 3 , a channel 346 further includes a charging connector 358. The charging connector 358 is in electrical communication with the power source 108. Furthermore, a safety arm 124 includes a first end 360, a second end 362 opposite the first end 360 defining a longitudinal direction there between. In the embodiment shown in FIG. 3 , a charging receptacle 364 extends inward from the second end 362 towards the first end 360 and is in electrical communication with the battery 344. The charging receptacle 364 has a complementary shape to the charging connector 358 and is adapted to slidably receive the charging connector 358 thereby connecting the charging connector 358 to the charging receptacle 364. When a safety arm 124 is in the stored position, the second end 362 of a safety arm 124 abuts the side surface 352 of the channel 346 and the charging receptacle 364 connects to the charging connector 358. The complementary shapes of the charging connector 358 and the charging receptacle 364 provides a frictional interference fit between the charging connector 358 and the charging receptacle 364. When the charging connector 358 is connected to the charging receptacle 364, the battery 344 is in electrical communication with the power source 108 which allows the power source 108 to charge the battery 344. The charging dock 342 may charge any number of safety arms 124 simultaneously.

As will be discussed in further detail below, a safety arm 124 further includes coupler that is adapted to attach or couple a safety arm 124 to the vehicle 100. A safety arm 124 is adapted to fall away from the vehicle 100 without damaging the vehicle 100 (i.e., the cab 102 or the trailer 104).

FIG. 4 depicts the second holder 304. As shown in FIG. 4 , the first rack 338 and the second rack 340 of the second holder 304 are structurally identical. For the sake of brevity, reference numerals on the first rack 338 correspond to identical elements on the second rack 340. Furthermore, it is understood that the first rack 338 and the second rack 340 are structurally identical to the first rack 324 and the second rack 326 of the first holder 302. The first rack 338 includes a first surface 402 and a second surface 404 opposite the first surface 402. The first surface 402 includes a number of grooves 406. The number of grooves 406 will be dependent upon a number of safety arms 124 that the safety arm holder 120 is adapted to retain. For example, in the embodiment shown in FIG. 2 , the safety arm holder 120 is adapted to retain four safety arms 124. Hence, the first rack 338 contains two grooves 406 and the second rack 340 contains two grooves 406 for a total of four grooves 406. It is envisioned that either the first rack 338 or the second rack 340 may contain any number of grooves 406 (i.e., 1, 3, 6, 9, 10, etc.). It is further envisioned that the first holder 302 and the second holder 304 may contain any number of racks (1, 3, 6, 9, 10, etc.).

Furthermore, a shape and dimension of a groove 406 corresponds to a shape and dimension of a safety arm 124. For example, in the embodiment shown in FIG. 4 , a groove 406 is semi-circular. The semi-circular shape corresponds to the circular shape and dimension of the safety arm 124. Due to the corresponding shape and dimension, when a safety arm 124 is in the stored position, the safety arm 124 nests within the groove 406. When the second holder 304 includes a charging dock 342, the surface 348 of a channel 346 is flush with groove 406 which allows a safety arm 124 to slide into the channel 346 from a first rack 338 or a second rack 340.

FIG. 5 depicts safety arms 124 removed from the trailer 104. In order to remove safety arms 124 from the trailer 104, safety arms 124 may be slidably moved in the direction of arrow B.

FIG. 6 depicts a breakaway assembly 600. In this embodiment the breakaway assembly 600 includes a coupler 602 at the first end 360 of a safety arm 124 and a safety arm receiver 604 on the vehicle 100.

In this embodiment, the coupler 602 couples to safety arm receiver 604 by moving the safety arm 124 in the direction of arrow C. The safety arm receiver 604 includes a keyhole 606 with a first portion 608 and a second portion 610. The keyhole 606 receives the coupler 602 of a safety arm 124.

FIGS. 7A-7C depict a safety arm 124 with coupler 602 and the safety arm receiver 604. The safety arm receiver 604 includes a first wall 605 and a second wall 607 that extend from the bottom surface 306 of the first hose holder 118. The second wall 607 includes an outer surface 612 and an inner surface 614. The keyhole 606 extends from the outer surface 612 to the inner surface 614. Although the safety arm receiver 604 is shown connected to the first hose holder 118, it is envisioned that the safety arm receiver 604, and other embodiments of arm receivers, may be connected to the second hose holder 204, the tank 110, or the cab 102.

The coupler 602 includes a first circular wall 620. The first circular wall 620 includes a first circular surface 622 and a second circular surface 624 opposite the first circular surface 622. The coupler 602 further includes a second circular wall 626 that extends from the second circular surface 624 to a circular surface 628 of a first tapered portion 630 of the coupler 602. The first circular wall 620 has a greater diameter than the second circular wall 626. The first tapered portion 630 extends from the circular surface 628 to a break portion 632 of the coupler 602. The break portion 632 extends from the first tapered portion 630 to a second tapered portion 634.

FIG. 7B depicts a safety arm 124 coupled to safety arm receiver 604. The keyhole 606 is dimensioned so that the first circular wall 620 may pass through the first portion 608 of the keyhole 606. The first circular wall 620 may pass through the first portion 608 by moving a safety arm 124 in the direction of arrow D. When the first circular wall 620 passes through the first portion 608 and the second circular wall 626 aligns with the second portion 610 of the keyhole 606, the safety arm 124 is then moved in the direction of arrow E thereby coupling the coupler 602 to the safety arm receiver 604.

FIG. 7C further depicts a safety arm 124 coupled to a safety arm receiver 604. The keyhole 606 extends from the outer surface 612 of the first wall 605 of the safety arm receiver 604 to the inner surface 614 of the first wall 605. When the coupler 602 is couple to the safety arm receiver 604, the second circular surface 624 abuts the inner surface 614 of the first wall 605, the circular surface 628 abuts the outer surface 612 of the first wall 605 and the second circular wall 626 nests within the second portion 610 of the keyhole 606.

FIG. 8 depicts an embodiment wherein a power outlet 802 is connected to the first hose holder 118 and adjacent to the safety arm receiver 604. In another embodiment, the power outlet 802 may be connected to the second hose holder 204 or anywhere else on the vehicle 100. The power outlet 802 is in electrical communication with the power source 108. In this embodiment, the power outlet 802 is adapted to receive a plug 804 of a safety arm 124. The plug 804 is connected to a wire 806 that places the plug 804 in electrical communication with the light source 345. As such, when the power outlet 802 receives the plug 804, the power source 108 supplies power to the light source 345 of the safety arm 124.

FIG. 9 depicts two safety arms 124 in an operational positon. When in the operational position, one safety arm 124 or two safety arms 124, as depicted in FIG. 9 , extend outwardly from the vehicle 100 thereby creating a safety zone. While FIG. 9 depicts two safety arms 124 coupled to the trailer 104, it is understood that any number of safety arms 124 may be coupled to the vehicle 100 (i.e., the trailer 104 or the cab 102). The safety arms 124 include a first side 902, a second side 904 opposite the first side 902, and power switch 906. While FIG. 9 depicts the light source 345 on the first side 902 and the second side 904 of the safety arm 124, it is envisioned that the safety arm 124 may include the light source 345 on only the first side 902 or only the second side 904. In this embodiment, the two safety arms 124 are coupled to the first side 210 and adjacent to the nozzle assembly 116.

The power switch 906 controls the flow of electricity from a battery 344 or the power source 108 to the light source 345. A user may engage the power switch 906 a number of times to power a light source 345. For example, when a safety arm 124 includes the light source 345 on the first side 902 and the second side 904 and is off (i.e., no light is being emitted from the light source 345 on either the first side 902 or the second side 904), a user may engage the power switch 906 a first time to cause a light source 345 to emit light from the first side 902 and the second side 904. After engaging the power switch 906 a first time to emit light from both the first side 902 and the second side 904, the user may engage the power switch 906 a second time to emit light from only one side (i.e., the first side 902 or the second side 904) of the safety arm 124. The user may then engage the power switch 906 a third time to power off the safety arm 124 (i.e., no light is being emitted from the light source 345 on either the first side 902 or the second side 904). When on, the light source 345 emits light 908 that illuminates an area adjacent to the vehicle 100. The light source 345 may be any suitable source of illumination including, but not limited to, at least one strip of light emitting diodes.

FIG. 10 depicts a safety arm 124 contacting an object 1002 (i.e., a stationary pole). In one embodiment, the coupler 602 may be formed from a suitably rigid material so as to support the safety arm 124 when the safety arm 124 is coupled to the safety arm receiver 604 without any support structure depending from the safety arm 124. Furthermore, the integral structure of the coupler 602 may be formed from multiple elements having similar configurations as one having ordinary skill in the art would understand.

In one embodiment, the first tapered portion 630, the break portion 632, and the second tapered portion 634 are formed of the same material. In another embodiment, the first tapered portion 630, the break portion 632, and the second tapered portion 634 are formed of different materials. In this embodiment, the break portion 632 is formed of a material that is less rigid, and therefore more susceptible to breaking, than a material that forms a remainder of the coupler 602 including the first tapered portion 630 and the second tapered portion 634. Furthermore, the break portion 632 has a smaller diameter than the first tapered portion 630 and the second tapered portion 634. As such, the break portion 632 is less rigid and more susceptible to breaking than the remainder of the coupler 602 including first tapered portion 630 or the second tapered portion 634.

In one example, when the vehicle 100 moves in the direction of arrow F and the object 1002 contacts the safety arm 124, a force is applied to the safety arm 124 causing the safety arm 124 to move in the direction of arrow G. This force may cause the coupler 602 to break within the break portion 632. Due to the location of the break portion 632, when the break portion 632 breaks, the vehicle 100 is undamaged. When the break portion 632 breaks, the safety arm 124 falls away from the vehicle 100.

FIG. 11 depicts a breakaway assembly 1100. In this embodiment, the breakaway assembly 1100 includes a coupler 1102 at the first end 360 of a safety arm 124 and a safety arm receiver 1104 on the vehicle 100.

In this embodiment, the coupler 1102 includes a magnet that couples to a safety arm receiver 1104 that is formed from a suitable ferromagnetic material. The safety arm receiver 1104 includes a first wall 1106 that includes a surface 1108. The coupler 1102 includes a surface 1110 that defines the first end 360 of a safety arm 124 and magnetizes the coupler 1102 to the surface 1108 of the safety arm receiver 1104. In this embodiment, the coupler 1102 may be suitably strong to support the safety arm 124 when the safety arm 124 is coupled to the safety arm receiver 1104 without any support structure depending from the safety arm 124.

FIG. 12 depicts a safety arm 124 contacting the object 1002. In this embodiment, the coupler 1102 may not be strong enough to support the safety arm 124 when the safety arm 124 contacts the object 1002. For example, when the vehicle 100 moves in the direction of arrow H and the object 1002 contacts the safety arm 124, a force is applied to the safety arm 124 causing the safety arm 124 to move in the direction of arrow I. This force causes the coupler 1102 to demagnetize from the safety arm receiver 1104. When the coupler 1102 demagnetizes from the safety arm receiver 1104 due to a force applied to the safety arm 124, the safety arm 124 falls away from the vehicle 100 with the coupler 1102 and without damaging the vehicle 100. In this embodiment, the safety arm 124 may be undamaged and the safety arm 124 may be recoupled to the safety arm receiver 1104.

Although FIGS. 11 and 12 depict the coupler 1102 coupled to a safety arm receiver 1104, it is envisioned that the coupler 1102 may couple a safety arm 124 to any ferromagnetic surface of the vehicle 100. For example, FIG. 13 depicts a breakaway assembly 1300. In this embodiment, the breakaway assembly 1300 includes the coupler 1102 and a safety arm receiver 1304. In this embodiment, the safety arm receiver 1304 may be a disk extending from a surface 118A of the first hose holder 118. While the safety arm receiver 1304 is depicted as extending from the first hose holder 118, it is envisioned that the safety arm receiver 1304 may extend any surface of the vehicle 100. The safety arm receiver 1304 may be made formed of a ferromagnetic material or a magnet that attracts the coupler 1102.

FIG. 14 depicts a breakaway assembly 1400. In this embodiment, the breakaway assembly 1400 includes a coupler 1402 and a safety arm receiver 1404. The coupler 1402 is generally triangular in shape and the safety arm receiver 1404 has a complimentary triangular shape.

In this embodiment, the coupler 1402 defines the first end 360 of a safety arm 124. A neck 1406 extends from the safety arm 124 to a first surface 1408 of the coupler 1402. The first surface 1408 extends between a second surface 1410 and a third surface 1412. A fourth surface 1414 and a fifth surface 1416 opposite the fourth surface 1414 extend from and generally perpendicular to the first surface 1408 to a first angled surface 1418 and a second angled surface 1420. The fourth surface 1414 and the fifth surface 1416 extend between the second surface 1410 and the third surface 1412. The first angled surface 1418 is opposite the second angled surface 1420. The first angled surface 1418 and the second angled surface 1420 extend from the fourth surface 1414 and the fifth surface 1416 respectively to a rounded corner 1422. Furthermore, the first angled surface 1418, the second angled surface 1420, and the rounded corner 1422 extend between the second surface 1410 the third surface 1412.

The safety arm receiver 1404 is adapted to receive the coupler 1402 and includes a bottom wall 1405 and a top wall 1407. The safety arm receiver 1404 further includes a first outer edge 1423, a second outer edge 1424 opposite the first outer edge 1423, a third outer edge 1426, and a fourth outer edge 1428 opposite the third outer edge 1426. The third outer edge 1426 and the fourth outer edge 1428 extend between the bottom wall 1405 and the top wall 1407. The first outer edge 1423 and the second outer edge 1424 extend between and generally perpendicular to the third outer edge 1426 and the fourth outer edge 1428. The third outer edge 1426 and the fourth outer edge 1428 extend between and generally perpendicular to the first outer edge 1423 and the second outer edge 1424. The first outer edge 1423, the second outer edge 1424, the third outer edge 1426, and the fourth outer edge 1428 define an aperture 1411 that receives the coupler 1402.

The safety arm receiver 1404 further includes an angled wall 1409. The angled wall 1409 includes a first angled surface 1430, a second angled surface 1432 opposite the first angled surface 1430, a rounded corner 1434. The safety arm receiver 1404 further includes a first surface 1436, and a second surface 1438. The first angled surface 1430 and the second angled surface 1432 extend from the third outer edge 1426 and the fourth outer edge 1428 respectively to the rounded corner 1434. The first angled surface 1430, the second angled surface 1432, and the rounded corner 1434 extend between the first surface 1436 and the second surface 1438. The first surface 1436 and the second surface 1438 extend between the first angled surface 1430 and the second angled surface 1432. Furthermore, the first surface 1436 extends between the first outer edge 1423 and the rounded corner 1434 and the second surface 1438 extends between the second outer edge 1424 and the rounded corner 1434.

As depicted in FIGS. 15 and 16 , when the coupler 1402 is coupled to the safety arm receiver 1404, the coupler 1402 nests within the safety arm receiver 1404. When the coupler 1402 nests within the safety arm receiver 1404, the second surface 1410 of the coupler 1402 abuts the first surface 1436 of the safety arm receiver 1404, the third surface 1412 of the of coupler 1402 abuts the second surface 1438 of the safety arm receiver 1404, the rounded corner 1422 of the coupler 1402 abuts the rounded corner 1434 of the safety arm receiver 1404, the first angled surface 1418 of coupler 1402 abuts the first angled surface 1430 of the safety arm receiver 1404, and the second angled surface 1420 of coupler 1402 abuts the second angled surface 1432 of the safety arm receiver 1404.

As depicted in FIG. 16 , the first angled surface 1418 is not as long as the first angled surface 1430 and the second angled surface 1420 is not as long as the second angled surface 1432. As a result, the fourth surface 1414 and the fifth surface 1416 of coupler 1402 do not abut a surface of the safety arm receiver 1404.

FIG. 17 depicts a safety arm 124 contacting the object 1002. In this embodiment, when the safety arm 124 contacts the object 1002 the safety arm 124 falls away from the vehicle 100 with coupler 1402. For example, when the vehicle 100 moves in the direction of arrow J and the object 1002 contacts the safety arm 124, a force is applied to the safety arm 124 causing the safety arm 124 to move in the direction of arrow K. This force causes coupler 1402 to detach or decouple from the safety arm receiver 1404. When coupler 1402 decouples from the safety arm receiver 1404 due to a force applied to the safety arm 124, the safety arm 124 falls away from the vehicle 100 without damaging the vehicle 100. In this embodiment, the safety arm 124 may be undamaged and the coupler 1402 may be recoupled to the safety arm receiver 1404.

FIG. 18 depicts a breakaway assembly 1800. In this embodiment, the breakaway assembly 1800 includes a coupler 1802 at the first end 360 of a safety arm 124 and a safety arm receiver 1803 on the vehicle 100. While FIG. 18 depicts the safety arm receiver 1803 on the first hose holder 118, it is envisioned that the safety arm receiver 1803 may be coupled to the second hose holder 204.

The coupler 1802 includes an extension 1805 that extends from the safety arm 124. The coupler 1802 further includes a hook 1807 that extends from the extension 1805. The hook 1807 includes a first leg 1809 and a second leg 1811 that is perpendicular to the first leg 1809. The coupler 1802 further includes a first surface 1804 of the coupler 1802 extends longitudinally relative to the central vertical axis 222 from a first surface 1806 of the extension 1805 to a first rounded corner 1808.

The first rounded corner 1808 convexly curves downward relative to the central vertical axis 222 approximately 90° from the first surface 1804 to a second surface 1810 of the coupler 1802. The second surface 1810 extends longitudinally relative to the central transverse axis 220 from the first rounded corner 1808 to a third surface 1812 of the coupler 1802. The third surface 1812 extends longitudinally relative to the central vertical axis 222 from the second surface 1810 to a fourth surface 1814. The fourth surface 1814 extends longitudinally relative to the central transverse axis 220 from the third surface 1812 to a fifth surface 1816 of the coupler 1802. The fifth surface 1816 extends longitudinally relative to the central vertical axis 222 from the fourth surface 1814 to a sixth surface 1818. The sixth surface 1818 extends longitudinally relative to the central transverse axis 220 from the fifth surface 1816 to a seventh surface 1820. The seventh surface 1820 extends longitudinally relative to the central vertical axis 222 from the sixth surface 1818 to an eighth surface 1822. The eighth surface 1822 extends longitudinally relative to the central transverse axis 220 from the seventh surface 1820 to a second rounded corner 1824. The second rounded corner 1824 concavely curves downward relative to the central vertical axis 222 from the eighth surface 1822 to a terminal surface 1826 of the safety arm 124.

The first surface 1804, the third surface 1812, the fifth surface 1816, the seventh surface 1820, and the terminal surface 1826 extend generally parallel relative to the central vertical axis 222. The second surface 1810, the fourth surface 1814, the sixth surface 1818, and the eighth surface 1822 extend generally perpendicular relative to the central vertical axis 222.

A hemispherical member 1828 extends longitudinally relative to the central vertical axis from the eighth surface 1822. As will be discussed in further detail below, the hemispherical member 1828 is adapted to nest within the safety arm receiver 1803. The third surface 1812, the fourth surface 1814, the fifth surface 1816, the sixth surface 1818, and the seventh surface 1820 define an opening 1830. As will be discussed in further detail below, when the coupler 1802 is coupled to the safety arm receiver 1803, a portion of the safety arm receiver 1803 nests within the opening 1830.

The safety arm receiver 1803 includes a post member 1832 and a hemispherical receptacle 1834. The post member 1832 includes a first leg 1831 and a second leg 1833 that is perpendicular to the first leg 1831. The safety arm receiver 1803 further includes a first wall 1836. The first wall 1836 extends longitudinally relative to the central vertical axis 222 from the bottom surface 306 of the first hose holder 118. The first wall 1836 includes a surface 1840 that extends longitudinally relative to the central vertical axis 222 from the bottom surface 306 to a second wall 1842. The first wall 1836 extends generally parallel to the central vertical axis 222 and the second wall 1842 extends generally perpendicular to the central vertical axis 222. The first wall 1836, the second wall 1842, and the bottom surface 306 define an inlet 1844. As will be discussed in further detail below, in order to couple the coupler 1802 to the safety arm receiver 1803, the coupler 1802 passes through the inlet 1844.

The post member 1832 extends longitudinally relative to the central vertical axis 222 from a surface 1846 of the second wall 1842. The post member 1832 includes a first surface 1848. The first surface 1848 extends longitudinally relative to the central vertical axis 222 to a second surface 1850. The second surface 1850 extends longitudinally relative to the central transverse axis 220 to a rounded surface 1852. The rounded surface 1852 concavely curves upward relative to the central vertical axis 222 approximately 180° from the second surface 1850 to a third surface 1854. The third surface 1854 extends longitudinally relative to the central transverse axis 220 to a fourth surface 1856. The fourth surface 1856 extends longitudinally relative to the central vertical axis 222 to the surface 1846 of the second wall 1842. The first surface 1848 and the third surface 1854 extend generally parallel to the central vertical axis 222 while the second surface 1850 and the fourth surface 1856 extend generally perpendicular to the central vertical axis 222.

The hemispherical receptacle 1834 includes a first surface 1858 that extends longitudinally relative to the central vertical axis 222 from the surface 1846 of the second wall 1842 to a second surface 1860. The second surface 1860 extends longitudinally relative to the central transverse axis 220 from the first surface 1858 to a third surface 1862. Furthermore, the second surface 1860 includes a hemispherical surface 1864. As will be discussed in further detail below, the hemispherical surface 1864 is adapted to receive the hemispherical member 1828 of the coupler 1802. The third surface 1862 extends longitudinally relative to the central vertical axis from the second surface 1860 to the surface 1846 of the second wall 1842. Furthermore, the first surface 1858 of the hemispherical receptacle 1834 abuts the fourth surface 1856 of the post member 1832.

FIGS. 19 and 20 depict the coupler 1802 coupled to the safety arm receiver 1803. When the safety arm receiver 1803 is coupled to coupler 1802, the second surface 1850, rounded surface 1852, and the third surface 1854 of the safety arm receiver 1803 nest within the opening 1830 of the coupler 1802. In this position, second surface 1850 of the safety arm receiver 1803 abuts the fourth surface 1814 of the coupler 1802 and the third surface 1854 of the safety arm receiver 1803 abuts the sixth surface 1818 of the coupler 1802. Furthermore, when the coupler 1802 is coupled to the safety arm receiver 1803, the hemispherical member 1828 of the coupler 1802 nests within and abuts the hemispherical surface 1864 of the safety arm receiver 1803.

FIG. 21 depicts a safety arm 124 with the coupler 1802 contacting the object 1002. When the vehicle 100 moves in the direction of arrow L and the object 1002 contacts the safety arm 124, a force is applied to the safety arm 124 causing the safety arm 124 rotate in the direction of arrow M. When the safety arm 124 is in the positon depicted in FIG. 21 and the vehicle 100 continues to move in the direction of arrow L, the safety arm 124 moves in the direction of arrow N and detaches or decouples from safety arm receiver 1803. When decoupled, the safety arm 124 and the coupler 1802 fall away from the vehicle 100 without damaging the vehicle 100. In this embodiment, the safety arm 124 may be undamaged and the safety arm 124 may be recoupled to the safety arm receiver 1803.

FIG. 22 depicts a first safety arm 124 a, a second safety arm 124 b, the bracket 128, and the bracket support 130 being removed from the vehicle 100. In order to remove the first safety arm 124 a and the second safety arm 124 b, the first safety arm 124 a and the second safety arm 124 b are moved in the direction of arrow O. In order to remove the bracket 128 and the bracket support 130 from the bracket holder 126, first a first door 2202 and a second door 2204 are opened and then the bracket 128 and the bracket support 130 are moved in the direction of arrow P and removed from the bracket holder 126.

FIG. 23 depicts the bracket 128. The bracket 128 includes a first side 128A, a second side 128B opposite the first side 128A, a first safety arm holder 2302 and a second safety arm holder 2304. The first safety arm holder 2302 extends generally parallel to a first horizontal axis 2306 and the second safety arm holder 2304 extends generally parallel to a second horizontal axis 2308. The first horizontal axis 2306 and the second horizontal axis 2308 intersect a central vertical axis 2309 at right angles. Stated another way, the first horizontal axis 2306 and the second horizontal axis 2308 are perpendicular to the central vertical axis 2309. The first safety arm holder 2302 extends generally perpendicular to the second safety arm holder 2304.

The bracket 128 is octagonal in shape. A first surface 2310 of the first safety arm holder 2302 defines a first side 2312 of the bracket 128. A second surface 2314 opposite the first surface 2310 defines a second side 2316 of the first safety arm holder 2302. The first side 2312 of the bracket 128 is opposite the second side 2316 of the bracket 128. A semi-circular surface 2318 extends from the first surface 2310 to the second surface 2314 of the first safety arm holder 2302 and defines a channel 2320. As will be discussed in further detail below, the channel 2320 may retain a safety arm 124.

The third surface 2322 and the fourth surface 2324 extend generally perpendicular to the first horizontal axis 2306.

The second safety arm holder 2304 includes a first portion 2336, a structurally identical second portion 2338, and an opening 2307 between the first portion 2336 and the second portion 2338. The first portion 2336 includes a first surface 2340. The first surface 2340 defines a third side 2342 of the bracket 128 and the second portion 2338 includes a first surface 2343 that define a fourth side 2345 of the bracket 128.

The third side 2342 and the fourth side 2345 are approximately 90° offset from the first side 2312 and the second side 2316 relative to the central vertical axis 2309. The first portion 2336 further includes a second surface 2344 opposite the first surface 2340. A semi-circular surface 2346 extends from the first surface 2340 to the second surface 2344 of the second safety arm holder 2304 and defines a channel 2348. The channel 2348 extends from the first surface 2340 of the first portion 2336 to the first surface 2343 of the second portion 2338. As will be discussed in further detail below, the channel 2348 may retain a safety arm 124. The semi-circular surface 2346 is vertically above the third surface 2322 and the fourth surface 2324 of the first safety arm holder 2302 relative to the central vertical axis 2309.

The first surface 2340 of the first portion 2336 and the second surface 2344 of the first portion 2336 extend longitudinally relative to the central vertical axis 2309 to a third surface 2350 and a fourth surface 2352 of the second safety arm holder 2304. Furthermore, the first surface 2343 of the second portion 2338 and the second surface 2347 of the second portion 2338 extend to the third surface 2350 and the fourth surface 2352. The third surface 2350 extends to fifth surface 2354 of the second safety arm holder 2304 and the fourth surface 2352 surface extends to a sixth surface 2356 of the second safety arm holder 2304. The fifth surface 2354 and the sixth surface 2356 extend to the semi-circular surface 2346.

A seventh surface 2358 of the second safety arm holder 2304 extends longitudinally relative to the central vertical axis 2309 from the first surface 2332 of the bracket 128 to the third surface 2350. An eighth surface 2360 that is opposite the seventh surface 2358 extends from the first surface 2332 of the bracket 128 to the fourth surface 2352. The first surface 2340, the second surface 2344, the fifth surface 2354, the sixth surface 2356, the seventh surface 2358, and the eighth surface 2360 extend generally perpendicular to the central vertical axis 2309. The third surface 2322 and the fourth surface 2324 extend generally parallel to the second horizontal axis 2308.

FIG. 24 depicts the second side 128B of the bracket 128. The bracket 128 includes a first bracket support holder 2402 and a structurally identical second bracket support holder 2404 that extend longitudinally with respect to the central vertical axis 2309 from a surface 2406 of the bracket 128. Accordingly, for the sake of brevity, only the first bracket support holder 2402 will be discussed in further detail below.

The first bracket support holder 2402 includes a first surface 2408, a second surface 2410, a third surface 2412, and a fourth surface 2414. The first surface 2408 extends at an approximately 45° angle from the surface 2406 to the second surface 2410 and extends between the third surface 2412 and the fourth surface 2414. The second surface 2410 extends at an approximately 45° angle from the surface 2406 to the first surface 2408. The second surface 2410 faces a side of the bracket 128 that is not defined by the first safety arm holder 2302 or the second safety arm holder 2304. The second surface 2410 includes an annular edge 2416 that defines a bracket support receptacle 2418. As will be discussed in further detail below, the bracket support receptacle 2418 may be adapted to receive a bracket support 130. The third surface 2412 and the fourth surface 2414 extend longitudinally relative to the central vertical axis 2309 to the first surface 2408 and the second surface 2410.

FIG. 25A depicts the first safety arm 124 a coupled to the bracket 128. In order to couple the safety arm 124 a to the bracket 128, the first safety arm 124 a is moved in the direction of arrow Q. A safety arm 124 includes a rounded surface 2502 that extends between the first side 902 and the second side 904 of the safety arm 124. A width between opposing sides of the rounded surface 2502 is greater than a width between the first side 902 and the second side 904. Furthermore, the width between opposing sides of the rounded surface 2502 is greater than a width of the opening 2303 and the opening 2307, whereas the with between the first side 902 and the second side 904 is less than a width of the opening 2303 and the opening 2307. Accordingly, when inserting a safety arm 124 into the bracket 128, the safety arm is oriented so that the first side 902 and the second side 904 are parallel to the central vertical axis 2309 allow a safety arm 124 to nest within the first safety arm holder 2302 or the second safety arm holder 2304. The safety arm 124 may be rotated in the direction of arrow S so that the first side 902 and the second side 904 are perpendicular to the central vertical axis 2309 so that the first safety arm holder 2302 and the second safety arm holder 2304 retain a safety arm 124.

Furthermore, a safety arm 124 has a midpoint between the first end 360 and the second end 362. The safety arm 124 a may be moved in either direction of arrow R in order to align the midpoint of the safety arm 124 a with a center of the bracket 128. As depicted in FIG. 25A, when coupling the safety arm 124 a to the bracket 128, the light source 345 may be adjacent to the semi-circular surface 2318.

FIG. 25C depicts the first safety arm 124 a and the second safety arm 124 b coupled to the bracket 128. The second safety arm 124 b is coupled to the bracket 128 in an identical manner as the first safety arm 124 a. The safety arm 124 b may be moved until the midpoint of the safety arm 124 b aligns with the midpoint of the first safety arm 124 a. When the first safety arm 124 a and the second safety arm 124 b are coupled to bracket 128 and the midpoints are aligned with a center of the bracket 128, the first safety arm 124 a and the second safety arm 124 b form an “X” shape.

FIG. 26 depicts the bracket 128 coupled to the bracket support 130. In this embodiment, the bracket support receptacle 2418 slidably receives the bracket support 130. The bracket 128, the bracket support 130, the first safety arm 124 a, and the second safety arm 124 b form a safety device 2602. When assembled, the safety device 2602 may stand vertically on a surface 2604. When standing, the first safety arm 124 a, the second safety arm 124 b, and the bracket support 130 contact the surface 2604 to support the safety device 2602. While FIG. 26 shows the first end 360 of the first safety arm 124 a and the second safety arm 124 b, contacting the surface 2604, it is envisioned that the first safety arm 124 a and the second safety arm 124 b may be rotated 180° so that the second end 362 of the first safety arm 124 a and the second safety arm 124 b may contact the surface 2604.

FIG. 27 depicts the safety device 2602 in operation. When in operation, the safety device 2602 may be positioned adjacent to the vehicle 100. In one embodiment, when in operation, the safety device 2602 emits light 2702 from the light source 345 of the first safety arm 124 a and the second safety arm 124 b. In another embodiment, when in operation, the safety device 2602 does not emit light. While FIG. 27 shows light 2702 emitted from only one side of the safety device 2602 it is envisioned, in an embodiment wherein the safety arms 124 a and 124 b include a light source 345 on the first side 902 and the second side 904, so that the safety device 2602 may emit light 2702 from multiple sides. In this embodiment, the safety device 2602 may illuminate multiple areas.

Various inventive concepts may be embodied as one or more methods, of which an example has been provided. The acts performed as part of the method may be ordered in any suitable way. Accordingly, embodiments may be constructed in which acts are performed in an order different than illustrated, which may include performing some acts simultaneously, even though shown as sequential acts in illustrative embodiments.

While various inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the inventive embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.

All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.

The articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” The phrase “and/or,” as used herein in the specification and in the claims (if at all), should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc. As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.

As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

When a feature or element is herein referred to as being “on” another feature or element, it can be directly on the other feature or element or intervening features and/or elements may also be present. In contrast, when a feature or element is referred to as being “directly on” another feature or element, there are no intervening features or elements present. It will also be understood that, when a feature or element is referred to as being “connected”, “attached” or “coupled” to another feature or element, it can be directly connected, attached or coupled to the other feature or element or intervening features or elements may be present. In contrast, when a feature or element is referred to as being “directly connected”, “directly attached” or “directly coupled” to another feature or element, there are no intervening features or elements present. Although described or shown with respect to one embodiment, the features and elements so described or shown can apply to other embodiments. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “adjacent” another feature may have portions that overlap or underlie the adjacent feature.

Spatially relative terms, such as “under”, “below”, “lower”, “over”, “upper”, “above”, “behind”, “in front of”, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the exemplary term “under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms “upwardly”, “downwardly”, “vertical”, “horizontal”, “lateral”, “transverse”, “longitudinal”, and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.

Although the terms “first” and “second” may be used herein to describe various features/elements, these features/elements should not be limited by these terms, unless the context indicates otherwise. These terms may be used to distinguish one feature/element from another feature/element. Thus, a first feature/element discussed herein could be termed a second feature/element, and similarly, a second feature/element discussed herein could be termed a first feature/element without departing from the teachings of the present invention.

An embodiment is an implementation or example of the present disclosure. Reference in the specification to “an embodiment,” “one embodiment,” “some embodiments,” “one particular embodiment,” or “other embodiments,” or the like, means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments, of the invention. The various appearances “an embodiment,” “one embodiment,” “some embodiments,” “one particular embodiment,” or “other embodiments,” or the like, are not necessarily all referring to the same embodiments.

If this specification states a component, feature, structure, or characteristic “may”, “might”, or “could” be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to “a” or “an” element, that does not mean there is only one of the element. If the specification or claims refer to “an additional” element, that does not preclude there being more than one of the additional element.

As used herein in the specification and claims, including as used in the examples and unless otherwise expressly specified, all numbers may be read as if prefaced by the word “about” or “approximately,” even if the term does not expressly appear. The phrase “about” or “approximately” may be used when describing magnitude and/or position to indicate that the value and/or position described is within a reasonable expected range of values and/or positions. For example, a numeric value may have a value that is +/−0.1% of the stated value (or range of values), +/−1% of the stated value (or range of values), +/−2% of the stated value (or range of values), +/−5% of the stated value (or range of values), +/−10% of the stated value (or range of values), etc. Any numerical range recited herein is intended to include all sub-ranges subsumed therein.

Additionally, any method of performing the present disclosure may occur in a sequence different than those described herein. Accordingly, no sequence of the method should be read as a limitation unless explicitly stated. It is recognizable that performing some of the steps of the method in a different order could achieve a similar result.

In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures.

To the extent that the present disclosure has utilized the term “invention” in various titles or sections of this specification, this term was included as required by the formatting requirements of word document submissions pursuant the guidelines/requirements of the United States Patent and Trademark Office and shall not, in any manner, be considered a disavowal of any subject matter.

In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.

Moreover, the description and illustration of various embodiments of the disclosure are examples and the disclosure is not limited to the exact details shown or described.
